GB/T 17280-2017 Standard test method for distillation of crude petroleum—15-theoretical plate column
Basic Information
Scope
This standard specifies the test method for distilling stable crude oil with a vapor pressure of no more than 82.7 kPa.
This standard stipulates the test conditions for obtaining the mass of liquefied gas, distillation fractions, and residue fractions under the conditions of a reflux ratio of 5:1 and a final distillation temperature of 400 °C at atmospheric pressure using a distillation column with 14 to 18 theoretical trays, and calculating the mass yield or volume yield of each fraction, then plotting the real boiling point (TBP) distillation curve with the cutting temperature.
This standard is applicable to petroleum mixtures except liquefied petroleum gas, light naphtha, and fractions with an initial distillation point higher than 400 °C.
